When we got the DTC fiber wi-fi, we were told we had a backup battery system for when we lost electricity. We have since lost electricity 4 times and no internet or backup power source. Does anyone

The backup is phone only

Ok thanks! Not sure exactly which it's for. We were under the impression it was back up for wi fi and phone? It's a black box that stands up next to our phone and wi fi boxes...it has battery, cold start, etc. On it

There should be a battery backup for the Fiber ONT up. That will keep dial tone working if you have a phone that doesn't work off electricity. To be able to keep your wifi devices up you'll need a battery backup on the router.
